TIRE-REPAIR DEVICE.

To all whom it may concern:

Be it known that I, FREDERICK A. STRONG, a citizen of the United States, and resident of Bridgeport, Fairfield county, Connecti- ,cut, have made a certain new and useful Invention Relating to Tire-Repair Devices, of which the following is a specification, taken in connection with theaccompanying drawing, which forms part of the same.

This invention relates especially to tire erably having central holding hooks cooperating with the clencher rim or other part of the pneumatic tire and having a series of flexible securing chains adj ustably secured to said. plates and adapted to embed themselves sutliciently in the pneumatic tire to securely hold it in position adjacent the puncture or blowout, there being preferably a series or curved dumb bell attaching slots in said anchor plates wit-h which attaching link members cooperate so as to adjust the efiective length of the securing members. In the accompanying drawing showing illustrative embodiments of this invention in a somewhatdiagrammatic way, Figure 1 shows a repair device as applied to a pneumatic tire. Fig. 2 is an enlarged detail view of an anchor plate and connected parts. Fig. 3 is a'similar view of another form of anchor plate. Fig. 4 is a similar view of a still further modified form of anchor plate. Fig. 5 is a transverse section through a tire to which a device is attached. Fig. 6 is a detail of part of this device.

In the illustrative embodiment of the invention shown in Figs. 1 and 2, the anchor plates 3 which are preferably curved to substantially conform with the sides of the tire may as indicated be provided with a central relatively narrow holding hook 6 adapted to engage the inturned flange 28 of the clencher rim 8 and the tire shoe 1 mounted on the wheel 2. It is sometimes desirable to provide a special attaching device, such as the attaching loop 11, which may .as shown in *ig. 2 have the inturned ends 31' adapted to cooperate with suitable holes 30 in the i other part. The attaching loop may then anchor plate so that when inserted therein the attaching loop may be forcibly drawn downward by any convenient tool so asto force the holding hook into locking position in cooperation with the clenchei' flange or Specification of Letters Patent.

has been thus applied to the tire over a weakened portion or puncture 34 in connection, if desired, with an internal patch or shoe thetire is inflated in the usual way and the securing chains thus become firmly embedded in the tire shoe so as not to project to an undesirable extent beyond the normal tread surface and at the same time greatly minimize working or movement of the parts under service conditions.

The securing chains 4 may as indicated be of ordinary curb chain or preferably of machine made curb chain having accurately sized hardened links and any desired number of these securing chains may be conveniently connected with the anchor plates by suitable attaching link members which may cooperate with curved attaching slots in the plates. As indicated in Fig. 2, the attaching slots may be given a dumb bell shape and be formed with enlarged bearing apertures 10 while the curved connecting portion 7 of the slot is relatively narrow because of the somewhat enlarged head 12 projecting thereinto. The. attaching link members 5 which are preferably welded or otherwise permanently secured in closed position may be formed with suitable bearing port-ions 9 so as to properly cooperate with either of the bearing apertures and any desired portion of these attaching link members, such as the bearing portions 9,. maybe suiiiciently narrow so as to pass through the curved connecting portions of the attaching slots when for the purposes of adjustment the attaching members are moved to the other ends of these slots. This may be readily accomplished by swinging the attaching link into the dotted position indicated in Fig. 5 so as to allow the narrow hearing or adi'usting portion of the attaching link to pass edgewise through the narrow connecting portion of the attaching slot and be retained 1n position in cooperation with the lower enlarged bearing aperture so as to correspondingly. shorten the effective length of this securing chainy- In this way accidental displacement of the attaching links is mini mized "or prevented while at the same time the links may be readily and quickly adjusted so as to shorten the effective length of the securing chains by an eighth or a quarter of an inch and secure their proper coop- 5 eration with tires of different size.

Fig. 3 shows another form of anchor plate which may be provided with similarly curved dumb bell attaching slots 7 having the relatively enlarged bearing apertures 10 with which may cooperate the adjusting links 14 which may as indicated have the welded portions 15. By forming a suitable mlfnstimmus intlmsidcand taching link members permanently secured at the ends of each of said securing vchains and having flattened narrowed bearing portions cooperating with the enlarged bearing apertures a it each end of said attaching slots to normally hold each of said attaching link members in adjusted position while permit ting said attaching link members to be moved into the opposite bearing portions of each of said attaching slots to adjust "the effective length of said securing chains.

2. The tire repair device comprisinlg a mirotrhidanchor )lflitSOlllfVtCltWOIling slots, curb securing chains, and attach-- ing link, members permanently connecting the ends of each of said securing chains to said anchor plates, said attaching link members comprising bearing portions cooperating with the enlarged bearing apertures in said attaching slots and comprising narrow adjusting portions to pass edgewise through the narrow connecting portions of said attaching slots to adjust the effective length of said securing chains.

6. The tire repair device comprising a pair of anchor plates each provided with a central holding hook adapted to be secured to the wheel rini adjacent the sides of a pneumatic tire, one at leastof said anchor plates being formed with dumb bell attaching slots, securing chains, and attaching link members connecting the ends of each of said securing chains to said anchor plates,

said attaching link members comprising bearing portions cooperating with the en larged bearing apertures in said attaching slots and comprising narrow adjusting portions to pass edgewise through the narrow connecting portions of said attaching slots to adjust the efiective length of said securing chains.

7. The tire repair device comprising a pair of anchor plates curved to conform to the sides of the tire and each provided with a holding member adapted to be secured to the wheel rim adjacent the sides of a pneumatic tire, one at least of said anchorplates being formed with attachingslots provided with enlarged bearing apertures, securing chains, and attaching link members permanently connecting the ends of'each of said securing chains to said anchor plates, said attaching link members comprising bearing portions cooperating with the bearing apertures in said attaching slots to adjust the effective length of said securing chains.

8. The tire repair device comprising a pair of anchor plates each provided with a holding. device adapted to be secured to the wheel rim adjacent the sides of a pneumatic tire, one at least of said anchor plates being formed with substantially closed attaching slots provided with bearing apertures, securing chains, and attaching members connecting each of said securing chains to said anchor plates, said attaching members com prising bearing portions cooperating with the bearing apertures in said attaching slots to adjust the effective length of said securing chains.
